Cars that produce between 76g/km and 150g/km of CO2 will pay an extra £5. Vehicles that produce 151-170 g/km will pay £15, 171-190g/km will pay £25 extra. The highest polluting vehicles that churn out high levels of CO2 will understandably have to fork out more. Vehicles that emit 191-225g/km will pay £40 more and 226-255g/km will pay £55.

The top charges will only really apply to supercars, or thirsty SUVs and performance vehicles.

However, British motorists may be frustrated to have to pay any more for their VED after two years of increases.

In 2018 diesel cars owners whose cars didn't comply with the latest Real World Driving Emissions 2 face paying one band higher car tax. This could cost you up to £500 extra annually.

For example, if your car emits 131-150 g/km CO2 but it doesn't adhere to the new standard it will now cost you £500, which is the rate that cars that produce 151-170 g/km CO2 usually pays.

VED also increased in 2017 where new standardised rates were introduced alongside inflated first year fees.

The changes also saw a luxury car surcharge applicable for any car that costs of £40,000. Costing motorists an additional £310 on top of their annual VED rate.

As a result, only pure electric cars costing under £40,000 are exempt from paying car tax in the UK.

The changes meant that some drivers faced paying up to 25 times more to tax their car than before.

This standard rate charge will vary for drivers depending on what type of car they are and what fuel they use.
